Answer: B. 100

Explanation:

To find this out, we shall assume that the number of checks that should be written for the two accounts to cost the same will be x.

The cost of Account A assuming x number of checks is:

= 3 + 0.02x

For Account B this is:

= 2 + 0.03x

Equate both expressions:

3 + 0.02x = 2 + 0.03x

3 - 2 = 0.03x - 0.02x

0.01x = 1

x = 1 / 0.01

x = 100 checks
